BRIEF SUMMARY
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to an instrument intended to remove parasitic ticks from the skin of animals or man, in particular from pets or live-stock.
2. Description of the Related Art
Ticks, whether in their larvae, pupa or adult state, adhere to the skin owing to a rostrum that penetrates the epidermis. Traditionally, these ticks are removed with ether and tweezers of various designs, but it frequently happens that the tick's head and rostrum remain embedded in the skin.
Certain tweezers enable the removal of ticks without first using ether, but their design is quite complex, while their manner of gripping the tick, by squeezing its body, contributes to the regurgitation of blood and saliva towards the skin of the animal and thus the transmission of certain diseases.
SUMMARY OF THE INVENTION
The instrument, the subject of the present invention, allows to remedy these drawbacks.
With this in mind, the present invention relates to an instrument intended to remove parasitic ticks from the skin of animals or man, characterized by the fact that it consists of one piece provided, on the one hand, with a handle that ends in a round grip and, on the other hand, with a curved and flattened extremity that ends in a fork roughly perpendicular to the axis of rotation of said grip. This fork is formed by two prongs delimiting a so-called "prong interspace" intended for the gripping of the tick and suitable to remove the tick by rotating around a axis that is roughly perpendicular to the plane of the skin onto which the tick is adhered.
Owing to the present invention, the tick can be removed in a simple manner by inserting the prongs of the fork on one and the other side of the rostrum and by making the instrument rotate around an axis, so that the tick is neither squeezed nor lifted by simple traction but rather that it is essentially removed by rotation.
In accordance with the specific embodiments of the invention: that the prong interspace presents a V-shaped vertical section, that would allow a better grip on the tick while it is being removed. opening that would expand towards the free end of the fork, so that the instrument can be used for ticks of different sizes. handle. itself.
BRIEF DESCRIPTION OF THE DRAWINGS
The invention will be better understood and its other advantages will be seen more clearly through the below description of an embodiment of an instrument in accordance with its principle, given only by way of example and making reference to the accompanying illustrations wherein:
FIG. 1 is a perspective view of the instrument;
FIG. 2a is a top view of the fork and comprises two cross sections of this view;
FIG. 2b is a cross sectional view taken perpendicularly through the fork of FIG. 2a and along line A--A;
FIG. 2c is a cross sectional view taken perpendicularly through the fork of FIG. 2a and along line B--B;
FIG. 3 shows the manner in which the tick is gripped and held, and
FIGS. 4 and 5 show two profile view of the instrument gripping ticks of different sizes.
DESCRIPTION OF THE PREFERRED EMBODIMENT
The dimensions given by the scale are only by way of example but not limited to such.
With respect to the illustrations, the instrument comprises: instrument; "prong interspace" 6.
The prong interspace 6 presents a cross section in the shape of a vertical V, to fit around the head and the thorax of the tick 7, when the latter sticks to the skin 12. Thus, the tick's abdomen is not squeezed.
The opening of the prong interspace 6 widens towards the extremity, which makes it possible to firmly hold all ticks, regardless of their size. As a matter of fact, as it can be seen by comparing FIGS. 4 and 5, as regards the size of the tick, the fork holds more or less the tick on both sides. In the case of a large tick, as shown in FIG. 4, the tick is somewhat caught in the prong interspace 6, and the dimensions of the prong interspace, at the cross section B, make it possible not to squeeze the tick. In the case of a small tick, as shown in FIG.
